Why ZentroTECH

Four things no Bangalore agency bundles.

Every other agency sells you a website. We sell you the website AND the AI that fills it with leads AND the system that gets you paid.

Lead Engine Websites

Sites engineered to produce leads, not brochures. Every page funnels to a measurable conversion event — form, WhatsApp, call, chatbot, voice agent.

Business on Autopilot

Built for solo founders and small teams. We map your manual process and replicate it as automated workflows that run while you sleep.

Lead Follow-up System

Indian SMB closes after 5–7 touches; most agencies stop at 2. We run the full 7-touch nurture cadence on every lead via WhatsApp, SMS, email, and AI voice.

Payment Recovery

Unpaid invoices? Auto-reminders on Day 0/3/7/14/21/30 via WhatsApp + email + AI voice call. Stops the second payment lands. 30–50% lower DSO.

Why trust us

Common Questions

Things buyers actually ask us

Everything we get asked on the first call — pricing, timelines, what's included, how we're different.

How much does a lead-engine website cost?

It depends on scope, integrations, and ongoing automation needs. Starter SEO sites are affordable; full lead-engine builds with 3D, AI voice, and follow-up automation are a larger investment. Fill the requirements form and we send a custom quote within 1 business day — no obligation.

How is this different from a normal website agency?

Most agencies sell you a website, then leave. We build the website AND the AI follow-up + payment recovery automation that fills it with leads and gets you paid. We also won't ask you to subscribe to 5 different SaaS tools — we use self-hosted and affordable alternatives. One contract, one team.

Do you serve businesses outside Bangalore?

Yes. We're headquartered in Bangalore but actively serve 138 cities across South India — Chennai, Hyderabad, Coimbatore, Kochi, Mysore, Madurai, Trichy, Salem, Mangalore, Vijayawada, Visakhapatnam, Thiruvananthapuram, and more. Anywhere in India for the right project.

What's your 'business on autopilot' service for solo founders?

We map your manual process — how you handle sales enquiries, send quotes, chase payments, post on social, manage bookings — then build automated workflows that do those same things while you focus on growth. Built for 1-5 person teams who can't afford an ops manager.

Why does a payment recovery system matter?

In India, getting paid takes multiple polite reminders. Most businesses stop at 1-2 follow-ups out of awkwardness and lose 20-40% of their receivables. Our system runs a 6-stage reminder cadence over 30 days via WhatsApp + email + AI voice — automatically — and stops the second payment lands. Recovery typically improves 30-50%.

Can you build us an Android app along with the website?

Yes. We bundle Android app development into a single contract with the website if you need both. Native Kotlin or cross-platform Flutter, your call — we'll recommend based on scope and cost.

What languages does your AI voice agent speak?

Hindi, Kannada, Tamil, Telugu, and English by default. Add Malayalam, Marathi, Bengali, Gujarati, Punjabi as needed. Multi-language adds a small per-minute surcharge.

Do I have to pay for a bunch of SaaS subscriptions?

No. That's our anti-pitch. Most agencies set you up with HubSpot + Zapier + Calendly + Twilio + ClickFunnels — your monthly tool bill grows huge. We use self-hosted n8n, Zoho or open-source CRM, WhatsApp Business API, and affordable voice platforms. You'll spend less on tools after working with us, not more.

What's a Care Plan?

Monthly subscription that keeps your website + automations updated. Includes uptime monitoring, backups, security patches, content changes, SEO health audits, and (on higher tiers) ongoing automation tuning, content publishing, and an annual deep audit to keep you ahead of competitors. Quote-based per scope.

How long until we go live?

Starter SEO website: 2-3 weeks. Lead-engine animated website: 4-6 weeks. Full 3D + AI automation bundle: 6-10 weeks. Android app: 6-12 weeks depending on scope. We commit to a timeline in the proposal — no rolling delays.

Ready to 10x your inbound?

Free 30-min lead engine audit. We'll show you exactly where your website + automation can pay back in 90 days — or tell you honestly if it can't. Quote within 1 business day.
